This is concept art for the "In Vitro Meat House" by Mitchell Joachim of Terreform. The house is made of pig cells that were grown in a lab and fused onto scaffolding. It's like living in a scrapple cabin!

Here's how Joachim describes the sausage hut, which is made of sustainable, lab-grown animal tissue:

This is an architectural proposal for the fabrication of 3D printed extruded pig cells to form real organic dwellings. It is intended to be a "victimless shelter", because no sentient being was harmed in the laboratory growth of the skin. We used sodium benzoate as a preservative to kill yeasts, bacteria and fungi. Other materials in the model matrix are; collagen powder, xanthan gum, mannitol, cochineal, sodium pyrophosphate, and recycled PET plastic scaffold.

As you can see above, visitors enter and exit not through a door, but a sphincter. Whoa. I guess it's a greener option than building your home out of Slim Jims.
